What Part Q requires for a home project
The Part Q requirements and terms the buildwiz guides rely on, with paragraph references where the document gives one. Check the current edition on gov.uk before you build to it.
Terms explained
- PAS 24
- BSI security standard for doors and windows. Part Q requires it (or equivalent) only for easily accessible doors and windows in new dwellings (Approved Document Q para 0.2), so it is not a building regulations requirement for an extension, though insurers may ask for it. Configuration-specific: a 3-panel bifold certificate does not cover a 4-panel variant of the same system.
Pages where Part Q comes up
3 guides reference Part Q, grouped by build phase.

The buildwiz build guides walk through a UK extension in sequence and link to Part Q (and every other Approved Document) at the exact stage it bites. That is usually a more productive way to use this material than reading the document cover to cover.
